Article about The Incredible 3D Printing Gumball Gallery in Vending Times. Funny but the writing is actually more professional than the majority of 3D printing websites. #3DPrinting #3DGumballGallery

Hack Your Toys for Halloween!

This post is to encourage kids to design and 3D print costumes and accessories for their toys. Halloween is a great time of year for this sort of design challenge but it is really suitable for a number of holidays and special events. Imagine if your toys were going to a comic convention and wanted to cosplay as their favorite superhero. (Educators could ask students to convert their toys into famous historical or literary character.)

Some of my favorite characters to work with are from LEO the Maker Prince by Carla Diana. The 3D printable models from the story allow fans to extend the adventures of the characters. Look for the design at http://www.thingiverse.com/leothemakerprince/.

I've published my costume for Sheep at http://www.thingiverse.com/thing:499952. Included in the photo gallery are some photos of costume prototypes for Carla.

The Maker Faire Robot by LeFabShop is able to cosplay Baymax from the movie Big Hero 6 simply by being printed in white http://www.thingiverse.com/thing:331035.

The Athena Makeover by Zheng3 is also great for Barbie figures that want to cosplay characters from Percy Jackson films. http://www.thingiverse.com/thing:269721

So, what are you waiting for? Start Hacking Your Toys!

Be sure to share your photos and designs.

Add some fun to your next 3D printing demo with the 3D Printer Dance. The 3D Printer Dance added a kinesthetic element to a 3D printer demo at an elementary STEM camp. The dance helps reinforce principles of 3D printing. The full script is available at http://designmaketeach.com/2013/06/22/the-3d-printer-dance/

In the dark this morning? Make an emergency LED light in #VSTE14 Hackerspace. Very limited supply!! By 3B, also check out the great sessions in 3B.

Solve real problems in your makerspace.

PRINT IT FORWARD: 3D PRINTER FUNDRAISING KIT
I want to help put more 3D printers in schools. My idea is to send a bunch of 3D printed models to an educator, for free, to kickstart their fundraising. They then buy a printer and print a bunch of models for someone else.

I'm ready to go with a set of prints. If you know an educator that might be interested please share the link. (US K12 Public School)
Do you want a 3D printer for your school or classroom? Do you want your students to have the power to turn their ideas into reality? Is cost the only thing holding you back? I want to help by sendi...

Questions/Help  - 
 
Help Manually Setting Bed Plane

I have a #Printrbot Metal Simple with the Z-probe. At the start of a print, I run a G29 command to probe the bed level and determine the bed plane. This reports values in the form.
< 11:34:56 AM: Bed x: 10 y: 142.40 z: 0.42
< 11:35:04 AM: Bed x: 10 y: 10 z: 1.63
< 11:35:12 AM: Bed x: 142.40 y: 10 z: 1.72

These values will vary +/- 0.05 mm between calibration runs.
This works well enough for most prints but are not quite repeatable enough for print in place designs with very tight tolerances or low layer height prints where a 0.1mm height difference between corners may cause the print to fail.

I would like to manually set the z plane by setting the bed plane in Gcode at the start of the print. ie. Manually set the z value for 3 points as above. Any hints on what gcode to use to do this?

Is it possible to have the bed probed at more points? I noticed that the Afinia leveling scripts tests 9 points. Code suggestions?

Thanks,
Josh

Stupid question: do you know for sure that the variation is in the probe? You're asking the bed bearings and the cantilevered Z assembly to have slop of less than 2 thicknesses of a human hair. Even things like the weight of filament above the extruder could have measurable effects on that order.

3D Printing  - 
 
3D printing characters allows you to continue the story. LEO, Carla and Sheep from the book LEO the Maker Prince have had fabulous adventures. They have visited classrooms, workshops, STEM camps and even played in the snow. Kids at STEM camp even created their own versions of LEO and Sheep in Tinkercad.

The characters in these photos were printed on a Printrbot LC v1 and a Printrbot Metal Simple at a 0.2mm layer height with support enabled.

Enjoy remixing these characters to create your own unique designs and be sure to share their fun adventures.
